I need help on this question. Thanks in advance!

my calculation is like this: Percentage difference: 31-27=4

4% = £50,000 100% = £1.25mil

Need to find total revenue: Profit = Revenue - Cost Not too sure about this part.

Given

  • (1) $revenue*0.27 = profit$

  • (2) $revenue*0.31 = salaries$

  • (3) $profit + 50000 = salaries$ (since salaries has higher allocated %)

You can substitute the left side of (3) for $salaries$ in (2), then solve for $profit$:

  • $revenue*0.31 = profit + 50000$

  • $profit = revenue*0.31 - 50000$

Now, set this and (1) equal to each other and solve for $revenue$

  • $revenue*0.31 - 50000 = revenue*0.27$

WolframAlpha says revenue is about 1,250,000

Ahh, homework ;)

  • Sanity check year 3: 20%+22%+31%+27% = 100%
  • Salaries: 31%, Profit: 27%. Salaries - Profit = 4%.
  • 4% -> 50k GBP
  • Question reformulated: if 4% are 50k GBP, how much are 100%?

  • $\begingroup$ I'd say that "allocation of sales revenue" on top just might mean: "this is how our revenue was distributed". So, in my mind, 100% would be your answer. $\endgroup$

  • $\begingroup$ ok thanks for the explanation. 100% would be £1.25mil, there's no options for this answer. $\endgroup$

  • $\begingroup$ Judging from the comma to separate the thousands in your posted picture, there is a 0 missing at the 4th answer. Which then should be the correct one. Kick the programmer ;) $\endgroup$

So what was the percentage difference between profit and salaries that year?
